HOSE-COUPLING.

SPECIFICATION forming part of Letters Patent No. 603,366, dated May 3, 1898.

Application filed October 16, 1897- To all whom/jimmy. concern- B it n Wnth t-LBE ER BIEHL, r-, a resident of Pittsbu'rg,in thecounty ofAllegheny and State of Pennsylvania, have in vented a new and useful Improvement in Hose-Couplings; and I do hereby declare the following to be a full, clear, and exact description thereof.

, parts can be quickly and securely joined ner.

My invention relatesto hose-couplings.

The object of my invention is to construct a hose-coupling which is simple in construction and at the same time one in which the so as to form a tight joint.

' To these ends my invention comprises certain novel features, all of which will be fully hereinafter set forth and claimed.

To enable others skilled in the art to make and use my invention, I will describe the samemorefully, referring to the accompanying drawings,iu which- Figure Iisaside View of my improved coupling with the parts in position for coupling.

Fig. 2 is a like view showing the parts coupled. Fig. 3 is a bottom plan. view, partly in section, of the parts coupled; and Fig. 4c is a perspective view of the spring-bail.

Like letters indicate like parts in each of the figures.

I will describe and illustrate my invention as applied to coupling the hose of a water tank with the hose on a locomotive for feed-' ing the boiler; although I do'not wish to limit myself. to any particular use. 1

In the drawings, 'a designates a portion of a length-of hose to which the tubular con nection b is"attachediin any suitable man- 0 formed thereon with the opening 0' therein,

the pintle d, is the lever e. The, lever c has the 'seat or groove 'f formed therein, with which the spring-bail g is adapted to engage. This spring-bail g is formed of metal with suf-. ficient strength and resiliency for the required purpose, more fully hereinafter set forth.

' The spring-bail g is so bent as to form the portion h, substantially at right angles to the main'portion of the bail. By this construction this bent portion it embraces a part of The connection b hast-he enlargement Serlalllo. 655,392. (No ma i.)

I the connection I) when the parts are coupled,

as will more fullyappear. v i The endsof the spring-bail g are bent to form hooks t, which are adapted to engage ,the studs k on opposite points in the circumference of the ring is. This ring it encircles the connection Z, being loosely mounted thereon and free to turn. The connection Z is attached to the hose 1%. A shoulder n is formed within the connection Z, said shoulder forming a seat for an elastic washer 0.

When my improved coupling is in use and it is desired to connect the hose on a watertank with the hose on a locomotive, the parts are brought into their relative positions as shown in Fig. l. The spring-bail g has its hooked ends engaging with the studs 7c,while the bent portion h engages with the seat f in the lever e While the outer end of the connection b is in position to enter the connection Z. By throwing the lever 6 over into the position shown-in Fig. 2 the spring-bail is' carried to the other side of the pivotal point of the lever e while still held within the seat f; The effect of this operation is to draw the two conncctions b and Z closely together, the inner end of the connection I) being forced into close contact with .the elastic washer 0 within the connection Z, whereby a very tight connection is made. As the inner end of the spring-bail passes .beyondthe pivotal point of the lever e in the coupling operation the bent portion h of the bail springs up around the connec-,

tion I), in the position shown in Fig. 2. The

spring-bail in this position locks the lever e in position, so that it cannot be displaced by a sudden jolt or shock in such a manner-as to disconnect the coupling before desired. The

pull of the bail 'is on a line substantially central of the connections; so that the joint is equally tight at all points around the By the employment of a swivel-ring 7o, arranged to turn freely on the connection Z, the studs 70 may be quickly brought into the requisite position for coupling. This is a point of advantage, as the hose may be twisted and yet the coupling operation may be performed without the delay of untwisting to bring the parts into the proper position for coupling.

\Vhen the bail is not in use, its hooked ends 1 are held in the studs 79, said bail hanging therefrom.

IVhat I claim as my invention, and desire to secure by Letters Patent, is

1. In a hose-coupling, the combination with the tubular connections, of a lever pivoted to one of said connections, and a spring-bail secured to the other connection and releasably engaging said lever, substantially as set forth.

2. In a hose-coupling, the combination with the tubular connections, of a lever pivoted to one of said connections, a spring-bail secured to the other connection and releasably engaging said lever, said bail having its looped end bent at an angle to the main portion thereof, substantially as set forth.

3. In ahose-coupling, the combination with the tubular connections, of a lever pivoted to one of said connections, a spring-bail secured to the other connection and releasably engaging said lever, said bail having its looped end bent at right angles to the main portion thereof, substantially as set forth.

4. In ahosc-coupling, the combination with the tubular connections, of alever pivoted to one of said connections, said lever having a 35 recess formed therein, a spring-bail secured to the other connection and engaging said recess in said lever, said bailhavin g its looped end bent at an angle to the main portion thereof, substantially as set forth.

5. In a hose-couplin the combination with the tubular connections, of a lever pivoted to one of said connections,a spring-bail,a swivelring on the other connection, said bail having its ends secured to said ring, said springbail being releasably connected at its looped end to said lever, substantially as set forth.

(3. In ah se-coupling, the combination with the tubular connections, of a lever pivoted to one of said connections, a spring-bail having hooks formed on its ends, a swivel-rim g on the other connection, projections on said ring with which said hooks engage, said springbail being releasably connected at its looped end to said lever, substantially asset forth.

7. In a hose-coupling, the combination with the tubular connections, of a lever pivoted to one of said connections, a swivel-ring on the other connection, and a connecting member between said lever and said ring adapted to engage said ring and hold said connections together, substantially as set forth.

In testimony whereof I, the said PETER RIEHL, J12, have hereunto set my hand.
